Therefore, GCD of numbers 495, 261, 274, 487 is 1

Given Input Data is 495, 261, 274, 487

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 495 is 3 x 3 x 5 x 11

Prime Factorization of 261 is 3 x 3 x 29

Prime Factorization of 274 is 2 x 137

Prime Factorization of 487 is 487

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(495, 261) = 14355

GCD(495, 261) = ( 495 x 261 ) / 14355

GCD(495, 261) = 129195 / 14355

GCD(495, 261) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 274

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(9, 274) = 2466

GCD(9, 274) = ( 9 x 274 ) / 2466

GCD(9, 274) = 2466 / 2466

GCD(9, 274) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 487

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

GCD(1, 487) = 487 / 487

GCD(1, 487) = 1

GCD of 495, 261, 274, 487 is 1
